In Tableau Server you will configure Trusted Authentication. The steps for doing this are covered in this article. Trusted authentication simply means that you have set up a trusted relationship between Tableau Server and the Metric Insights. When Tableau Server receives requests from Metric Insights, Tableau assumes the credentials of the Metric Insights user.

1. Username is the same on Metric Insights and Tableau Server

To use SSO, each username created on Metric Insights must have an identical username in Tableau Server. For example, if you sign in with username 'admin' in Metric Insights, then to be able to SSO to Tableau server you must also have the username 'admin' in Tableau server. This is true for all usernames that you want to have SSO ability for.

If your username in Metric Insights does not have an identical username in Tableau server, then you do not get SSO to Tableau for this user.

1.1. Find IP address of Metric Insights instance

You only need to do this for versions of Tableau server 8.0 and prior. For Tableau server 8.1 and beyond, you can use the fully qualified domain name of the Metric Insights instance.

NOTE: If you already have an existing External Report Type defined for Tableau, you can enable SSO authentication for all reports associated with this type by modifying the Drill Down Authentication setting.
